Foraminiferan

Among the tiny sand grains was this tiny foraminiferan shell almost exactly a millimeter wide. ❋ AYDIN (2006)

Many foraminiferan shells tests look quite like snail shells. ❋ AYDIN (2006)

And like snail shells, most foraminiferan shells are also made of CaCO3. ❋ AYDIN (2006)

"Our observations demonstrate that coccoliths, and probably also planktonic foraminiferan tests, reach the Challenger Deep intact," said Gooday. ❋ Unknown (2010)

The researchers were therefore surprised to discover that foraminiferan tests sampled from the Challenger Deep contained calcareous components, including the dissolved remnants of coccoliths, the calcium carbonate plates of tiny algae called coccolithophores, and planktonic foraminiferan test fragments. ❋ Unknown (2010)

"Using genetic data we have been able to prove that the planktonic species Streptochilus globigerus and the benthic - sediment living - foraminiferan Bolivina variabilis are one and the same biological species." ❋ Shantanu (2010)
